Combination nail polish remover and applicator bottle

ABSTRACT

A dual purpose fluid container for an integrated makeup kit, particularly an integrated nail makeup kit, wherein the nail polish, polish applicator brush, nail polish remover solvent, and nail polish remover pads are combined in a size and shape that is easily carried in a modestly sized purse or handbag, but which can quickly and easily be separated into a conventional nail polish applicator bottle with brush, and a jar containing a plurality of nail polish remover pads saturated with solvent. When separated, each of the bottle and jar can rest on a flat surface, or be readily held in one&#39;s hand, such that each can be used independently of the other, in any sequence or order, without danger of spillage or mutual contamination.

BACKGROUND OF THE INVENTION

The present invention is directed to personal makeup products, and in particular, to an improved nail polish applicator.

For many years women have purchased bottles of nail polish having a cap with brush wand, which enables them to colorize their nails in the convenience of their homes while also permitting them to take the bottle with them it in a purse or the like, for touch up as needed while outside the home. However, the proper application of nail polish for achieving a smooth, glossy finish, requires that all polish previously applied to the nails be fully removed. While at home, a woman will typically have a separate bottle of nail polish removing solvent and abrasive pads for this purpose.

Whereas carrying a nail polish bottle in a purse for touch up does not represent a significant inconvenience, having only the nail polish available for use outside the home limits the circumstances under which the polish can be effectively applied outside the home. Most women would not go to the trouble of placing a nail polish bottle, a polish remover bottle, and a package of removal pads into what in current times is frequently a very modestly sized purse.

For many women, especially those who are outside the home for long periods during the day and must look their best throughout the day, the maintenance of perfectly defined, smooth, shiny nail coloring is an ongoing nuisance.

SUMMARY OF THE INVENTION

Accordingly, it is an object of the present invention, to provide a dual purpose fluid container for an integrated makeup kit, particularly an integrated nail makeup kit, wherein the nail polish, polish applicator brush, nail polish remover solvent, and nail polish remover pads are combined in a size and shape that is easily carried in a modestly sized purse or handbag, but which can quickly and easily be separated into a conventional nail polish applicator bottle with brush, and a jar containing a plurality of nail polish remover pads saturated with solvent.

When separated, each of the bottle and jar can rest on a flat surface, or be readily held in one's hand, such that each can be used independently of the other, in any sequence or order, without danger of spillage or mutual contamination.

DESCRIPTION OF THE PREFERRED EMBODIMENT

FIGS. 1-4 show a dual purpose fluid container in the form of an integrated nail makeup kit comprising an upper container 10 and a lower container 12, which define an upper chamber 14 and a lower chamber 16, respectively. The upper container 10 would typically have a cylindrical sidewall 18 and a circular bottom wall 20 which fluidly isolates the upper chamber 14 and from the lower chamber 16. The lower end or base of the upper container 10 at bottom wall 20 preferably has a flange or rim 22 with internal threads that mate with external threads on a neck 24 that extends from an annular shoulder at the periphery of the upper end of the lower container 12.

The upper container 10 has an access aperture 26 formed as a bore through an externally threaded neck 28 extending from the top wall. In the preferred product as marketed to consumers, the upper chamber 14 is substantially filled with one form of makeup fluid 30, in particular, nail polish. The lower chamber 16 holds a different form of makeup that would be used in conjunction with the makeup in the upper chamber. In particular, the lower chamber holds a plurality of pads 36 saturated with any conventional solvent for nail polish. The lower container 12 preferably has a substantially cylindrical sidewall 32 and flat circular bottom wall 34. The top need not have an upper wall, but rather is preferably open. The bottom wall 20 of the upper container 10 completes the encapsulation of the chamber 16 and thus maintains fluid isolation between chambers 14 and 16 when the upper and lower containers are secured together at the threaded interface 22, 24.

Because the solvent in the lower chamber 16 is typically highly volatile, a secure seal should be formed at the confronting surfaces of the lower side of the wall 20 against the rim of the neck 24 of the lower container 12, or at the tight engagement of the threaded interface 22, 24. For example, a resilient annular gasket or the like could be glued to the rim of the neck 28 of container 12, or the entire underside of the bottom wall 20 could be formed of a resilient gasket material. Moreover, a resilient o-ring 33 could also be located at the confronting surfaces at the bottom of the rim 22 of the upper container 10 and the shoulder at the upper periphery of the lower container 12. One of ordinary skill in the art could readily design these confronting components in relation to the engagement of the threads to assure that the threads to not engage to the limit before the seal is effectuated.

The cap 38 has a cylindrical or substantially frustoconical handle 40 that is partially hollow such that a stem or wand 42 extends longitudinally from within the handle to a polish applicator brush or the like 44. At the base of the handle 40, internal threads 46 are provided at a diameter for engaging the external threads on neck 28, in a manner that is typical of conventional nail polish bottles.

As may be appreciated from FIGS. 2 and 3, the threaded brush cap 38 is selectively attachable to the neck 28 for opening and closing the aperture 26. The brush 44 enters the chamber 14, which encloses a first working volume, when the cap is attached to the neck and is entirely removed from the first working volume when the cap is detached from the neck. The lower chamber 16 partially encloses a second working volume such that when the threads 22, 24 are engaged the top 48 of the lower chamber 16 is closed by the bottom wall 20 of the upper chamber and when the threads are disengaged the lower container 12 separates from the upper container 10 whereby the second working volume is exposed through the open top 48. Clearly, whether the containers 10, 12 are secured together as in FIG. 1 or detached as in FIG. 3 or 4, the working volume 14, 16 and thus the nail polish 30 and the polish remover pads 36 are always isolated from each other.

It should be appreciated that the composite makeup kit, particularly the combination of nail polish applicator bottle 10 and nail polish removal jar 12, can readily be grasped in the hands and detached from each other for use, as shown in FIGS. 2 and 4. FIG. 4 shows one subsequent step by which the user has placed the upper container or bottle 10 on a flat surface for ready access to the brush cap 38 while the other container or jar 12 for the saturated pads 36 is on the same flat surface nearby. The base of each container 10, 12 should be flat or effectively flat for this purpose. Because the solvent that saturates the pads 36 is volatile, the user may wish to remove one or two pads 36, then reassemble the containers 10, 12 before using the pads for removing previously applied polish from a portion of one nail, one entire nail, or all nails in the fingers of one hand. The cap 38 can then be removed from the upper container for applying polish while the pads 36 remain in a fluidly sealed environment.

It should also be appreciated that the number of nails from which polish can be removed by the inventory of pads 36 in chamber 16, may differ from the number of nails that can be polished by the inventory of polish 30 in upper chamber 14. This difference would most likely occur because all the pads 36 would be utilized before all of the polish 30, or, due to the volatility of the solvent, some of the pads would become ineffective for removing polish. If the latter condition occurs, the user at her convenience at home, could easily detach the upper and lower containers 10, 12 and pour solvent into chamber 16 through the open end 48 thereby replenishing the effectiveness of the pads. Furthermore, replacement pads can be made available as an after market item, provided they have the same area foot print as the cross section of the chamber 16.

Although many configurations of the upper container 10 and lower container 12 and their inter-engagement are within the scope of the present invention, in the preferred embodiment, the overall shape is cylindrical with a length of the composite bottle (without cap) of approximately 2-4 inches, and an outer diameter or equivalent cross sectional dimension between opposed walls in the range of about 1-2 inches. The overall axial length of the upper container 10 and the lower container 12 are about equal and in most instances would not differ by more than a 60%-40% ratio. For an example with reference to FIG. 1, the overall height h₁ of the lower bottle is preferably 1.0-1.5 inch, the overall height h₂ of the upper bottle including cap is preferably 2.0-2.5 inch, and the outer diameter d is about 1.5 inch. The cross section would typically be circular, but other cross sectional shapes such as oval, rectangular, or other polygon are also possible. It is not necessary that the cross sectional shape of the upper and lower containers 10, 12 or working volumes 14, 16 be identical. As a practical matter, the diameter of chamber 16 or similar cross dimension of a non-circular chamber, should be large enough to receive a pad that is large enough (e.g., at least ¾ in diameter) to be easily used for removing previously applied polish.
